In truth, it is a combination of both her mind and body being controlled, hence why Maloker can use her powers to attack them. And the part of April that is still aware is desperately trying to connect to Clark through the bond -- but she can't get to the mental tree, as there is a swarm of bats surrounding it. She is being prevented by the very thing that give her special abilities -- her voices have been triggered to fight against her and her friends.

"No. You can't kill..." Maloker prevents her from saying any further. From warning them to exactly why they shouldn't kill Maloker. He doesn't want them to know that he could possibly possess and claim April's body as his own, if they do destroy his current mortal shell.

April directs another psychic blast at them, this time hitting above where the stalactites are hanging, trying to break them off and fall onto her friends. Meanwhile, in the back of his mind, Ed can hear the insistent hum of his spirit guardian. The shadow spirit is trying to tell him something.
